Abstract (en)

[origin: EP0841157A2] This invention relates to improved flexible laminates formed from at least one corona treated polyolefin or polyester film bonded to another polymeric or cellulosic film via an aqueous based laminating adhesive. The improvement in the flexible laminates resides in the aqueous based laminating adhesive used to bond the respective films. The aqueous based laminating adhesive is comprised of an acrylic interpolymer prepared by emulsion polymerizing alkyl (meth)acrylates, alpha - beta unsaturated olefins, such as styrene and suitably substituted styrenes, and/or alpha - beta unsaturated nitriles, such as acrylonitrile with a glycidyl (meth)acrylate and having the pendent epoxy group converted to the hydroxy amine. The preferred pendant units are hydroxy propylamine groups.
